IPC: C09K23/00

Abstract: Aqueous solutions of phenols, their homologues and derivatives are prepared with the assistance, as solution promoting agents, of sulphonation products of aliphatic alcohols with at least six and at most ten carbon atoms in the molecule and/or of ethers of such alcohols with polyhydric alcohols, if desired together with a minor proportion of sulphonation products of aliphatic alcohols with more than ten carbon atoms and/or of ethers of the latter with polyhydric alcohols.  The solutions so prepared, which may be alkaline but not sufficiently alkaline to have a mercerizing action, possess wetting properties and retain their disinfecting power.  They may be used in human and veterinary medicine, in the destruction of vermin, in the starch, glue, paint, leather, textile, soap and food industries, and for the prevention of fungus and mould formation and putrefaction processes.  In examples: (1) a fatty alcohol sulphonate obtained from alcohols having 8--10 carbon atoms is used to make aqueous solutions of chlorcarvacrol, chlorthymol, p-chlor-m-cresol and chlorxylenol, which are suitable for adding to liquid glues, glue colours, starch pastes, liquid soaps, mouthwashes, and cosmetic preparations; (2) glycerol monooctyl ether is sulphonated and neutralized, and may be used to form a solution of p-chlor-m-cresol which kills cholera bacteria; (3) sulphonates derived from a mixture of 4 parts octyl and decyl alcohols and 1 part lauryl alcohol or from a mixture of fatty alcohols with 8 to 10 carbon atoms and oleic or ricinoleic alcohol are used as solvents for a mixture of p-chlor-m-cresol, chlorxylenol, chlorthymol and chlorcarvacrol.  Sulphonates of ethers of alcohols having 6 to 10 carbon atoms with glycol, pentaerithritol, mannitol and sorbitol are mentioned, and also derivatives of phenols containing halogen, alkoxy and nitro groups.ALSO:Aqueous solutions of phenols, their homologues and derivatives are prepared with the assistance, as solution-promoting agents, of sulphonation products of aliphatic alcohols with at least six and at most ten carbon atoms in the molecule and/or of ethers of such alcohols with polyhydric alcohols, if desired together with a minor proportion of sulphonation products of aliphatic alcohols with more than ten carbon atoms and/or of ethers of the latter with polyhydric alcohols.  The solutions so prepared retain their disinfecting power and may be used in the glue, paint and soap industries.  In examples: (1) a fatty alcohol sulphonate obtained from alcohols having 8--10 carbon atoms is used to make aqueous solutions of chlorcarvacrol, chlorthymol, p-chlor-m-cresol and chlorxylenol, which are suitable for adding to liquid glues, glue colours, and liquid soaps; (2) glycerol monoethyl ether is sulphonated and neutralized, and may be used to form a solution of p-chlor-m-cresol; (3) sulphonates derived from a mixture of 4 parts octyl and decyl alcohols and 1 part laurylalcohol or from a mixture of fatty alcohols with 8 to 10 carbon atoms and oleic or ricinoleic alcohol are used as solvents for a mixture of p-chlor-m-cresol, chlorxylenol, chlorthymol and chlorcarvacrol.
